my g/f has a 01 monte carlo ls. her blinkers would work when they felt like it so after doing research i found it was most likely the hazard switch. After fixing it they worked fine with no issues. As it got colder on some days they half work. the light up but dont blink now. I found a few places that sell a relay for the flasher so i bought it. but can't figure out where it goes. dealer said under dash on driver side but i cant find it. from the look of it, it slide onto something. I have a 5 month old thats suppose to ride in this car. someone please help me.

 

check under the hood for fuse blocks, should be 2 i think. if not there open the passenger side door, on my 5th gen there is another fuse block on the end of the dash, i think a 6th gen is the same. there should be tags / stickers that label what fuse / relay does what.

 

yeah, should be under the hood on the passenger side, may be a cover over it
